Lamborghini Huracan Drive Shaft Rear Left Right 4S0501204A

the part number 4S0501204A refers to the Rear Drive Shaft (Axle Shaft) for the Lamborghini Huracán. This is a critical driveline component that transfers power from the rear differential to the wheel hubs.

Because the Huracán shares its mid-engine architecture with the Audi R8 (Type 4S), this part number carries the 4S0 Audi-derived prefix, making it one of the more accessible mechanical parts to source.

1. Technical Identification

• Part Number: 4S0501204A

• Position: Rear Axle.

• Side Compatibility: In most Huracán configurations (LP610-4, LP580-2, Evo), this part is symmetrical, meaning the same part number is used for both the Left and Right rear sides.

• Components: The assembly includes the constant velocity (CV) joints, the axle bar, and the protective rubber boots.

• Installation Specifications

  • Hub Bolt: The large bolt that secures the shaft to the wheel hub is a Stretch Bolt (one-time use). You must replace this bolt (WHT005437 or similar) whenever the axle is removed.

  • Torque Setting: These require a high torque value (typically $200\text{ Nm} + 180°$ turn). Improper torque is the #1 cause of premature wheel bearing failure in Huracáns.
